Comparative study on electrical performance of normal and superconducting multiconductor lines for high-speed interconnects and uniplanar MICs

A comparative study of electrical performance is made between normal and superconducting multiple conductors, for applications in high-speed, high-density VLSI interconnects and uniplanar MICs. The self-consistent electromagnetic analysis is presented, which can handle the multiconductors as normal dielectrics, with high real or complex conductivity in the electromagnetic simulation. Examples of interconnecting lines and multiple uniplanar waveguides are shown for dispersion and losses. Extremely low losses and dispersion of superconducting multiple lines, over a very wide frequency range, demonstrate promising potential for high-speed interconnects
